hi your php crawler was very useful for our small project but i need help ,this works within my localhost only i need to make it work int entire web ….i look forward for u help please thank u in advance …..

I really like phpCrawler gives we exactly what I want in terms of a lightweight crawler I can point at whatever web site I want to analyze but I seem to be misinterpreting the use the the $CRAWL_PAGE_EXPIRE_DAYS parameter. On line 39 within function markOldURLsToCrawl of my version of _crawler.php it checks to see if the crawl time has expired and needs to be recrawled but then regardless of the results it deletes words on line 40 which causes the search to no longer work for the follow-on searches until the site is recrawled. That doesn’t seem right to me? Do I have a good version and am I interpreting it right?

Where the content of crawled web pages are stored????
Can crawler gives the flexibility to extract only the user comments from the entire webpage?
Which other parameters can we change such as CRAWL_DEPTH, $CRAWL_PAGE_EXPIRE_DAYS,etc?
